Examining the relationship between trade and labour regulation in light of the pressing need to promote sustainable development, Tonia Novitz interrogates how international legal architecture could be reformed so that no one in the world of work gets left behind. She highlights the dangers of pursuing labour and environmental issues on parallel tracks without recognising how they interact, ultimately arguing for the crafting of the content and application of trade rules through participatory processes, which involve the inclusive representation of all sectors of the labour market and all parts of the world.
